Answer:

Julia brother

Step-by-step explanation:

Given that Julia and her brother, Emilio, are both saving to buy a new computer that costs $1,000.

Julia savings per week =100 $

Hence no of weeks required to save full 1000 = 1000/100 = 10

x =10 weeks for Julia

For Julia brother

[tex]y=10^{x-2}[/tex]

When y =1000 we have

[tex]1000=10^{x-2}\\x-2=3\\x=5[/tex]

Hence Julia brother will reach their 1000 goal first in 5 weeks, and Julia in 10 weeks.
